An ankle fracture is a break in one or more of the bones that make up the ankle joint, typically the tibia, fibula, or talus. It can occur from incidents such as a twisting injury, falls, or direct trauma. Symptoms include severe pain, swelling, bruising, and difficulty bearing weight on the affected ankle. Treatment may involve immobilization with a splint or cast, realignment of the bones through manipulation or surgery, and rehabilitation exercises to restore strength and function to the ankle joint.
